Various embodiments provide systems and methods for casting amorphous alloys. Exemplary casting system may include an insertable and rotatable vessel configured in a non-movable induction heating structure for melting amorphous alloys to form molten materials in the vessel. While the molten materials remain heated, the vessel may be rotated to pour the molten materials into a casting device for casting them into articles.
